The O-Ring is a vital sealing component used in Waterjet Cutting Systems to ensure leak-free operation and maintain optimal pressure in high-performance machinery. Made from high-quality materials like nitrile rubber, viton, or polyurethane, O-Rings are designed to create a tight seal between two mating parts, preventing fluid or gas leakage. These seals are crucial for maintaining the integrity of the hydraulic systems in Waterjet Machines, especially in high-pressure environments where even the smallest leak can lead to significant operational issues.
